Very low useability I bought the app. Totally not worth it. I wrote to the author and there has been no reply so poor support. Also, it also says in the description of the basic app: "You can create your own custom zones or use predefined ones." that is not precisely true. You can not create you own custom zones to block but you can turn on and off sections of the pre-defined zones. So that is pretty lame. Its a waste of time and money.
Limited use App prevents touch input, but still registers a touch (for example it will wake up media player controls). App is ineligible for refund, even within 15 minutes.
Will use this app so much it's crazy! This wonderful app fixes so many oversights on the S4 can't praise it enough, works beautifully. Now I can finally use S-voice with a hands free without pressing random things from being in my pocket whilst cycling. Worth 6 stars!
Works as described Very useful app.
Hard to control and does not lock nav
Good idea badly designed Sadly doesn't work. You can still swipe the screen, any notification can be accessed, etc. Pity.
